The standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin and directrix is y² = 16x.
<h3>What is the parabola?</h3>It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
Given that the parabola's vertex is located at the origin and that the directrix is at x = -4, the focus is at (4,0).
Then the equation can be written as
On squaring both sides, we have

Answer:
<h2>x = 70°</h2><h2>y = 55°</h2><h2>z = 55°</h2>Step-by-step explanation:
Look at the picture.
We know: the sum of the angles measure in the triangle is 180°. Therefore we have the equation:
Solve it:
Angle α and β = x are the supplementary angles. Supplementary angles add up to 180°. Therefore:
